Blunted cone-flare in hypersonic flow

The numerical results are compared with the measured pressure and surface heat flux distributions in the H3 wind tunnel and a good agreement is found, although some discrepancies are present, especially on the length of the recirculation region. A sensitivity analysis has been performed to investigate the influence of the wall temperature, that has shown an influence of the wall temperature on both surface heat flux and surface pressure. A numerical model has been developed to take into account the heating of the test model, and a closer agreement with the experimental data is found.
